Diabetes

Diabetes is a group of conditions that affect how your body uses blood sugar, a vital energy source for your muscles, tissues, and brain. Different types of diabetes have different causes. However, all types involve the body not managing blood sugar properly, leading to too much sugar in the blood. High blood sugar can cause serious health issues.

Diabetes is categorized into different types. Chronic types include Type 1 and Type 2 diabetes. These conditions generally require ongoing management. Other types, like prediabetes and gestational diabetes, might be temporary or potentially reversible.

Prediabetes means your blood sugar levels are higher than normal but not high enough to be considered diabetes. If left untreated, prediabetes can develop into full-blown diabetes. Taking steps to manage blood sugar levels is important to prevent this progression.

Gestational diabetes develops during pregnancy. Often, this type of diabetes goes away after the baby is born. However, women who have gestational diabetes are at higher risk for developing Type 2 diabetes later in life. It's crucial to monitor blood sugar and follow a doctor's advice during pregnancy if diagnosed with gestational diabetes.

Diabetes symptoms vary depending on how high your blood sugar is. Some people, especially those with prediabetes, gestational diabetes, or type 2 diabetes, might not notice any symptoms at all. In type 1 diabetes, symptoms usually appear quickly and are often more noticeable.

Common symptoms of both type 1 and type 2 diabetes include:

• Increased thirst: Feeling unusually thirsty.
• Frequent urination: Needing to urinate more often than usual.
• Unintentional weight loss: Losing weight without trying to.
• Ketones in the urine: Your body sometimes makes substances called ketones when it doesn't have enough insulin. Having ketones in your urine is a sign of a serious lack of insulin.
• Fatigue and weakness: Feeling very tired and weak.
• Mood changes: Feeling irritable, or having other changes in your mood.
• Blurry vision: Difficulty seeing clearly.
• Slow-healing sores: Cuts and scrapes take longer than usual to heal.
• Frequent infections: Getting more infections than usual, including gum, skin, and vaginal infections.

Type 1 diabetes can develop at any age, but it often starts in childhood or during the teenage years. Type 2 diabetes, which is more common, can also start at any age. While it's more frequently seen in people over 40, type 2 diabetes is becoming increasingly common in children.

Diabetes: Early Detection and Management

If you're concerned that you or your child might have diabetes, it's crucial to talk to your doctor right away. The sooner diabetes is diagnosed, the sooner treatment can begin, and the better the chances of managing it effectively. Diabetes symptoms can vary, but some common signs include frequent urination, unusual thirst, unexplained weight loss, blurred vision, and sores that heal slowly. If you notice any of these, or other unusual changes in your health, make an appointment with your doctor.

Once you've been diagnosed with diabetes, you'll need regular check-ups with your doctor. This is important to make sure your blood sugar levels are under control. Monitoring blood sugar levels closely is key to preventing complications. Your doctor will work with you to develop a treatment plan that suits your specific needs and lifestyle. This might involve lifestyle changes, such as diet and exercise, and possibly medication. It's crucial to follow your doctor's instructions carefully and attend all scheduled appointments for the best outcomes. This ongoing care helps to manage your diabetes effectively and prevent potential long-term health problems.

Understanding diabetes starts with how your body normally uses sugar (glucose). Your pancreas, a gland behind and below your stomach, makes a hormone called insulin. This insulin is released into your blood.

Insulin's job is to allow glucose from your blood to enter your body's cells. Think of insulin as a key that unlocks the doors of your cells, letting the sugar inside. This process lowers the amount of sugar in your blood.

Your body needs glucose for energy. Your muscles and other tissues use glucose for fuel. Your body gets glucose from two main sources: the food you eat and your liver.

Your liver acts like a glucose storage and production center. It stores glucose as a substance called glycogen. When your blood sugar gets too low, like when you haven't eaten in a while, your liver breaks down this glycogen into glucose, keeping your blood sugar levels balanced.

In diabetes, something goes wrong with how your body uses insulin. Your body either doesn't make enough insulin (type 1 diabetes) or your body's cells don't respond properly to the insulin it does make (type 2 diabetes). This causes sugar to build up in your blood.

Unfortunately, the exact reason for most types of diabetes isn't fully understood. Scientists think a combination of things might play a role, but these factors aren't completely clear. These factors might include your genes and your environment.

Diabetes risk factors vary depending on the type. A family history of diabetes can increase the risk for all types. For example, if a parent or sibling has diabetes, you might have a higher chance of developing it yourself.

Environmental factors, like where you live, can also influence the risk of type 1 diabetes. Scientists aren't completely sure why, but things like exposure to certain viruses or geographic location might play a role.

In some cases, family members of people with type 1 diabetes are checked for specific immune system cells (called autoantibodies) that can signal a higher risk. Having these autoantibodies means you're more likely to develop type 1 diabetes later in life, but it doesn't guarantee you will. Many people with these autoantibodies never get diabetes.

For type 2 diabetes, certain racial and ethnic groups face a higher risk. This includes Black, Hispanic, American Indian, and Asian American people. Researchers are still working to understand why these groups are at higher risk.

Being overweight or obese significantly increases the risk of developing prediabetes, type 2 diabetes, and gestational diabetes. Extra weight puts extra stress on the body's ability to regulate blood sugar, making these conditions more likely.

Diabetes Complications: Understanding the Risks

Diabetes can lead to serious long-term health problems if blood sugar levels are not well managed. The longer someone has diabetes and the less controlled their blood sugar is, the greater the risk of complications. These issues can range from uncomfortable to life-threatening. Even prediabetes, a condition where blood sugar is higher than normal, can progress to type 2 diabetes.

Common Diabetes Complications:

• Heart and Blood Vessel Disease: Having diabetes significantly increases your risk of heart problems. High blood sugar can damage the blood vessels, leading to conditions like:

  • Coronary artery disease: This can cause chest pain (angina).
  • Heart attack: A serious and potentially life-threatening event.
  • Stroke: Damage to the brain due to reduced blood flow.
  • Atherosclerosis: Narrowing of the arteries, reducing blood flow throughout the body. People with diabetes are more prone to these problems.

• Nerve Damage (Diabetic Neuropathy): High blood sugar can harm the tiny blood vessels that supply nerves, especially in the legs. This can cause various symptoms:

  • Tingling, numbness, burning, or pain: Often starts in the toes and fingers and spreads upward.
  • Digestive issues: Problems with nausea, vomiting, diarrhea, or constipation can arise.
  • Erectile dysfunction (ED): Men with diabetes may experience ED.

• Kidney Damage (Diabetic Nephropathy): The kidneys contain small filters (glomeruli) that remove waste from the blood. Diabetes can damage these filters, potentially leading to kidney failure.

• Eye Damage (Diabetic Retinopathy): High blood sugar can damage the blood vessels in the eyes, potentially causing vision loss or even blindness.

• Foot Problems: Nerve damage and poor blood flow in the feet increase the risk of infections, sores, and other foot complications.

• Skin and Mouth Problems: Diabetes can make you more susceptible to skin infections (bacterial or fungal) and other skin issues.

• Hearing Problems: Hearing loss is sometimes more common in people with diabetes.

• Alzheimer's Disease: Research suggests that type 2 diabetes may increase the risk of dementia, including Alzheimer's.

Gestational Diabetes Complications:

Most women with gestational diabetes have healthy babies. However, uncontrolled blood sugar during pregnancy can pose risks to both the mother and the baby.

• Baby Complications:

  • Large baby: High blood sugar in the mother can cause the baby's body to produce more insulin, resulting in excessive growth. This can make delivery more difficult and may require a C-section.
  • Low blood sugar (hypoglycemia): A baby's own insulin production might be high after birth, leading to dangerously low blood sugar.
  • Increased risk of type 2 diabetes later in life: Babies born to mothers with gestational diabetes have a higher chance of developing obesity and type 2 diabetes later in life.
  • Death: In severe cases of untreated gestational diabetes, the baby may die either before or shortly after birth.

• Mother Complications:

  • Increased risk of gestational diabetes in future pregnancies: If a woman has gestational diabetes in one pregnancy, she's more likely to experience it again in future pregnancies.

It's crucial to manage blood sugar levels effectively to minimize the risk of these complications. If you have diabetes or are at risk, talk to your doctor about ways to prevent or manage these problems.

Preventing Type 2 Diabetes and Related Conditions

Type 1 diabetes can't be prevented. However, healthy habits can significantly reduce the risk of developing other types of diabetes, like type 2 diabetes, prediabetes, and gestational diabetes. These same healthy habits can also help manage these conditions.

Here's what you can do:

1. Eat a Healthy Diet: Focus on foods that are lower in fat and calories, and higher in fiber. Think fruits, vegetables, and whole grains. Variety is key – try different fruits and veggies to keep your meals interesting and prevent boredom. Eating a balanced diet provides essential nutrients and helps maintain a healthy weight.

2. Be Physically Active: Aim for at least 30 minutes of moderate-intensity aerobic exercise most days of the week. This could be a brisk walk, swimming, cycling, or any activity that gets your heart rate up. If 30 minutes feels like a lot, break it up into shorter sessions throughout the day. Regular physical activity is crucial for overall health and helps control blood sugar levels.

3. Manage Your Weight: Maintaining a healthy weight is important for preventing diabetes. If you're overweight, losing even a small amount – about 7% of your total weight – can significantly lower your risk. For example, if you weigh 200 pounds, losing 14 pounds could make a difference. This weight loss should be part of a healthy lifestyle, not just a short-term goal.

Important Note: Losing weight during pregnancy should be discussed with your doctor. Gaining the correct amount of weight during pregnancy is essential for the health of both you and your baby.

Long-Term Changes: Remember that making lasting changes to your diet and exercise routine is key to maintaining a healthy weight. These changes are beneficial not only for diabetes prevention but also for your overall well-being, including a healthier heart, increased energy levels, and improved self-esteem.

Medication: In some cases, medication can be helpful. For example, some oral diabetes medications, like metformin, may lower the risk of developing type 2 diabetes. However, healthy lifestyle choices remain crucial.

Regular Checkups: If you have prediabetes, it's essential to get your blood sugar checked regularly (at least once a year) to monitor your condition and detect any progression to type 2 diabetes early. Early detection allows for prompt intervention and management.

Understanding Type 1 Diabetes: Treatment and Diagnosis

Dr. Yogish Kudva, an endocrinologist, answers common questions about type 1 diabetes.

Treatment:

The best current treatment for type 1 diabetes is an automated insulin delivery system. This system combines a continuous glucose monitor (CGM), an insulin pump, and a computer program. The program constantly adjusts insulin levels based on the CGM's readings. Patients still need to tell the system how many carbohydrates they're eating at mealtimes to ensure proper insulin delivery.

Traditional glucose meter testing isn't enough. Blood sugar levels in type 1 diabetes can change dramatically—from normal to high or low—quickly throughout the day. A CGM is essential to track how well the treatment is working and to make necessary adjustments.

Current guidelines recommend using a CGM. The goal is to spend most of the day with blood sugar levels between 70 and 180 milligrams per deciliter (mg/dL). Ideally, this should be 70% or more of the time. Blood sugar levels below 70 mg/dL should be less than 4% of the time, and levels above 250 mg/dL should be less than 5% of the time. Checking A1C levels alone isn't sufficient for precise management.

Advanced Treatment Options:

In some cases, pancreas or islet cell transplantation might be considered. Islet cell transplantation is still largely research in the US. Pancreas transplantation is a clinical treatment option. This procedure can help people with type 1 diabetes who have "hypoglycemia unawareness" (when they don't recognize low blood sugar) or who frequently experience diabetic ketoacidosis (a serious complication). A combined pancreas and kidney transplant can be life-changing for those with type 1 diabetes who have developed kidney failure.

Staying Informed and Seeking Care:

Keep up-to-date on research and new treatments for type 1 diabetes by reading relevant publications. See a doctor specializing in diabetes at least once a year. Don't hesitate to ask questions or express concerns to your healthcare team. Being informed is crucial to managing your condition effectively.

Diagnosing Type 1 Diabetes:

Symptoms of type 1 diabetes often appear suddenly, prompting blood sugar checks. The American Diabetes Association (ADA) has screening guidelines for other types of diabetes and prediabetes, which develop more gradually. These screening guidelines cover several groups:

• Age 35 and older: Get an initial blood sugar test. If normal, repeat every three years.
• Women with gestational diabetes: Screen every three years after pregnancy.
• Individuals with prediabetes: Screen yearly.
• People with HIV: Get tested.

The ADA recommends various blood tests for diagnosing and monitoring diabetes:

• A1C Test: This test measures your average blood sugar level over the past 2-3 months. A higher A1C indicates higher blood sugar. An A1C of 6.5% or higher on two separate tests suggests diabetes. A reading between 5.7% and 6.4% indicates prediabetes. A reading below 5.7% is considered normal.
• Random Blood Sugar Test: A blood sugar level of 200 mg/dL or higher at any time suggests diabetes.
• Fasting Blood Sugar Test: A blood sugar test after an overnight fast. A fasting blood sugar level of less than 100 mg/dL is normal. A level between 100 and 125 mg/dL indicates prediabetes. A level of 126 mg/dL or higher on two separate tests suggests diabetes.
• Glucose Tolerance Test: After an overnight fast, a sugary drink is consumed, and blood sugar levels are checked regularly for two hours. A reading of over 200 mg/dL after two hours suggests diabetes. A reading between 140 and 199 mg/dL indicates prediabetes.

If your doctor suspects type 1 diabetes, they may test your urine for ketones (produced when the body uses fat for energy) and check for specific immune system cells (autoantibodies) associated with the condition. Doctors also routinely screen for gestational diabetes during pregnancy.
